Different people have very different chances of being diagnosed with breast cancer.
There is usually no one factor that causes breast cancer. It's likely a combination of the effects of a person's risks combined with an element of bad luck.
Inflammatory breast cancer, a pernicious form of the disease.
Breast cancer awareness month may be over, but don't put away your pink. The disease is with us year-round. While researchers have found several ways to treat it, here are some things to know.

The majority of research suggests the benefits of mammography screening greatly outweigh the harms for women over age 40.
African-American women are about three times more likely to be diagnosed with triple negative breast cancer, an aggressive form of the disease.
Researchers have long been looking for clues into how to treat triple negative breast cancer. Could fighter blood cells that infiltrate the tumor provide insight?
There may be a very good reason for not wanting to get up in the morning when it’s still dark.
Evidence for a link between breast cancer and artificial light appears to be growing. Do studies showing higher risk of breast cancer the farther west a woman lives in a time zone add to the science?
Breast cancer rates in China are rising, and are expected to continue rising for the next three decades.
The lack of awareness of this growing problem is a big issue.
Breast cancer could kill 76,000 Indian women a year by 20220, according to new research.
Physical activity has long been considered a way to lower risk for breast cancer.
Physical activity is considered an important way to lower risk for breast cancer. But what if your ability to be fit is influenced by genes you inherit? Would that raise your risk? In rats, it did.
A recent Canadian trial reports breast cancer over-diagnosis rates of up to 55 per cent, from routine screening mammograms.
October is breast cancer awareness month. Women should know there is no reliable evidence that routine mammograms reduce death from breast cancer, and there's good evidence that they cause harm.
Canadians are overwhelmingly opposed to insurance companies having access to their genetic test results. A new Canadian law prevents insurers from using genetic information to determine coverage or pricing.
Canadian insurance companies argue that a new law denying them access to genetic test results will raise the cost of insurance for everyone. That's doubtful.
We’ve known for over three decades that cancer risk increases with alcohol consumption.
A new study has found the alcohol industry deliberately misrepresenting the cancer risk of alcohol, while passing it off as health messaging.
More mammography, for instance, starting at a younger age or screening more often, isn’t necessarily better.
Calls to routinely offer breast cancer screening to more women might sound like a good idea, but can harm. Here are three questions to ask when figuring out whether more screening really is better.
Artificial light has transformed the night sky, a change researchers continue to link to health problems.
Fabio Falchi et al
Study uses satellite data to add to growing evidence that nighttime light exposure raises risk of breast cancer, with the strongest link among young women.
Some conditions should be classified as normal in some people and don’t need treatment.
Australian health-care organisations are urging action on treatments of people who don't need them.
The curse of survival.
A twinge can be all it takes to convince patients they have a new tumour
The high cost of cancer drugs in South Africa has come under the spotlight with an investigation by the Competition Commission in the country.
Digitized strand of DNA.
Genetic testing is revealing important information about disease risks, and consumers can now pay for a test to know their risk. They might be better off if their doctors considered these risks, too.
Women with breast cancer face many treatment decisions on the path to survivorship. One question has been: Can they have fewer doses of radiation and still keep their risks for recurrence low?
Women with breast cancer often have six weeks of radiation therapy after surgery to remove the cancer. A recent study suggests that shortening that time is not only effective but also cost-saving.
Scientists know that many toxins, such as those found in cigarettes, cause most lung cancers, whose cells are depicted here. But isolating causes for other cancers is an ongoing effort.
What causes cancer? A scary truth might be that we have created an environment for it. An anthropologist's search for answers to her own diagnosis raises questions for all of us.
Tumour evolution was first identified 40 years ago. We're finally making good progress with it.
